Which countries invented solar calendars?
Many countries invented and used solar calendars, because it was one of the most apparent observable incidents in daily life. They became almost universal in one form or another. Modifications were introduced such as lunar calendars and joint solar/lunar calendars.
How many solar sistems are there?
In the observable UNiverse there are somewhere in the order of 1011 galaxies, a typical galaxy might have 1011 stars, and it seems likely that most stars have planets and would therefore qualify as "solar systems". That makes for a total of roughly 1022 stars or solar systems (that is a one, followed by 22 zeroes), just in the observable Universe. Note that the total Universe is probably much larger, but it isn't currently know how much larger. All of the above are rough estimates, of course.
Why do they say that the solar cycle is 22 years long?
The most obvious solar cycle the sunspot cycle, of roughly 11 years (on average - the length of an actual cycle may vary). Once in every sunspot cycle, the Sun's magnetic field reverses (north become south, and south becomes north), so a full cycle (for north to be back where it started) is twice the sunspot cycle.
How long does a solar cycle last?
Most solar panels would last about 25 years Most solar panels would last about 25 years ---------------------------------------------------------------- from www.solarcells101.com Most solar panels are rated 25 years But its hard to say because most of the first solar panels in the 1980s are still putting out power they will have a power loss over time but free power for this long is very cool David www.solarcells101.com
When is solar radiation most intense?
Solar radiation is most intense at noon.
Which cycle is most important the water cycle mineral cycle solar energy flow or the community dynamics?
The nitrogen cycle
what are the characteristics of social phenomena?
One of the most important aspects of social phenomena is that it involves one person's observable behavior influencing another person. For example, racism is a social phenomenon because it is an ideology that people have constructed that directly affects another group, forcing them to change their behaviors.

What is corona of sun?
A corona is a type of plasma in the atmosphere of the sun which extends millions of kilometers into space, most easily seen during a total solar eclipse and also observable by a corona graph.

Which statement explains why the water cycle would slow dramatically during an ice age?
Ice reflects most of the solar radiation
What from the sun is the most important part of renewing our water supply?
Solar radiation, or heat, is the driving force behind evaporation, transpiration and most aspects of our water cycle.
Are sunspots most common during a sunspot minimum?
Sunspots are most common during a sunspot (solar magnetic) maximum, this occurs periodically, on an 11 year cycle.
Which perspective most clearly on how you learn observable responses?
behavioral.
Behaviorists are MOST successful in treating?
Observable behavior problems
What drivesthe hydrological cycle?
most of energy comes from the sun. The sun evaporates the earth's water...
What provides the energy that drives the rock cycle?
Endogeneous and Exogeneous Processes helps to drive the rock cycle.
